Other Results of the Project

Firstly, we
discovered a new coordinate transformation for EEG signals whose basis functions, that we call eigenbrains, are
well suited to represent the large-scale dynamics associated with
event related potentials. The method involves instantiating an
approximate model of the electrical properties of the brain as a
conductor medium and then studying the free vibrational modes of the
model. Eigenbrains can be used to meaningfully re-represent
the brain's electrical activity in a form which is similar to how human expert discribe such activity. We also compared our eigenbrains to
principal component analysis and independent component analysis highlighting differences and similarities.
